Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and more specifically, to a multi-segment corn milling cutter mechanism that is easy to disassemble. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. During operation, each cutting tooth sequentially and intermittently removes the excess material from the workpiece. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces. Among them, the corn milling cutter has a significant advantage in machining larger flat surfaces. Due to its large number of cutting inserts and large cutting area, it can effectively improve machining efficiency when milling large flat surfaces at high speeds.

[0003] A search revealed a detachable multi-segment corn milling cutter in the prior art, with patent publication number CN211966071U. The specification states that the number of tool body stacking blocks can be appropriately increased or decreased according to the actual situation of the processing site. Only the tool body stacking blocks need to be kept on hand to achieve different processing conditions, thereby reducing costs and maximizing economic practicality.

[0004] However, in actual use, because the cutting tool is composed of stacked blocks, the connecting parts between the blocks are easily affected by centrifugal force during high-speed rotation, causing the connection to gradually loosen. This not only affects machining accuracy but may also cause unstable vibration of the entire cutting tool, further aggravating tool wear and even leading to tool breakage and causing safety accidents. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-segment corn milling cutter mechanism that is easy to disassemble, so as to solve the problem that the stacked cutters in the prior art will become loose when rotating at high speed, which will make the cutter connection unstable, thus affecting the machining accuracy and aggravating the wear of the cutters.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a multi-segment corn milling cutter mechanism that is easy to disassemble, including a mounting base one, a mounting rod slidably connected inside the mounting base one, a mounting base two slidably connected outside the mounting rod, a plurality of blades being sleeved on the outside of the mounting rod, the plurality of blades being connected by pins, a plurality of sliding grooves being opened inside the mounting base two, an eccentric ring being slidably connected inside the sliding grooves, and the inner side of the eccentric ring being in contact with the outside of the mounting rod.

[0007] The eccentric ring is rotatably connected to a push block on its outer side, the push block is internally threaded with a connecting rod, and the push block is externally fixedly connected to a limit block.

[0008] The inner wall of the slide groove has an installation groove on the outer side, a placement piece is slidably connected inside the installation groove, a placement block is fixedly connected inside the placement piece, a limit groove is opened inside the placement block, and an elastic element is sleeved on the outside of the connecting rod.

[0009] The blade is disposed between mounting base one and mounting base two, and is in contact with the adjacent side of mounting base one and mounting base two.

[0010] The limiting block is slidably connected inside the limiting groove, and the push block is slidably connected inside the limiting groove.

[0011] The connecting rod is rotatably connected inside the placement piece, rotatably connected inside the placement block, and movably connected inside the mounting base two.

[0012] One end of the elastic element is fixedly connected to the placement plate, and the other end of the elastic element is fixedly connected to the inner wall of the mounting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the above solution, by installing an adjustable eccentric ring inside the mounting base, the tool is limited by the eccentric ring, which makes the stability of the tool after installation and stacking high. The eccentric ring can use inertia to counteract high-frequency vibration, and the dynamic balance of the tool can be corrected by moving the eccentric ring to adapt to different overhang lengths. This makes the milling cutter more flexible and stable to use, resulting in higher machining accuracy and better economic efficiency. Attached Figure Description

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a multi-segment corn milling cutter mechanism that is easy to disassemble, including a mounting base 1, a mounting rod 2 slidably connected inside the mounting base 1, a mounting base 3 slidably connected outside the mounting rod 2, and multiple blades 4 sleeved on the outside of the mounting rod 2. The mounting rod 2 provides mounting space for the blades 4, and the blades 4 are disposed between the mounting base 1 and the mounting base 3, and are in contact with the adjacent side of the mounting base 1 and the mounting base 3, so that the blades 4 can be limited by the mounting base 1 and the mounting base 3. The connection between the two blades 4 is made more stable by the pins 5. The interior of the mounting base 2 3 has multiple grooves 7, and an eccentric ring 6 is slidably connected inside the grooves 7. The grooves 7 limit the eccentric ring 6, so that the eccentric ring 6 will not deviate when sliding. The inner side of the eccentric ring 6 fits against the outer side of the mounting rod 2. The eccentric ring 6 is used to limit the mounting base 2 3. The eccentric ring 6 fits tightly against the mounting rod 2, so that the connection between the mounting rod 2 and the mounting base 2 3 is more stable, and thus the blades 4 are installed more stably.

[0024] When the insert 4 needs to be installed, the required number of inserts 4 are slid onto the mounting rod 2, making the inserts 4 fit tightly against the mounting base 1. Then, the mounting base 2 3 is slid onto the mounting rod 2, making the mounting base 2 3 fit tightly against the insert 4. Then, multiple eccentric rings 6 are moved inward, making the eccentric rings 6 fit tightly against the outside of the mounting rod 2. This allows the mounting rod 2 to limit the mounting base 2 3. Under the joint limitation of the mounting base 2 3 and the mounting base 1, the installation stability of the insert 4 is high. Moreover, the eccentric rings 6 can use inertia to counteract high-frequency vibration, resulting in high stability in use and a longer service life of the insert 4. While ensuring machining accuracy, the feed rate is increased, the overall cost of the tool holder is reduced, and the machining efficiency is greatly improved, resulting in good economic efficiency.

[0025] Example 2: Based on Example 1, in order to facilitate the movement of the eccentric ring 6, a push block 9 is rotatably connected to the outer side of the eccentric ring 6, so that the push block 9 can push the eccentric ring 6 to move. A connecting rod 12 is threadedly connected inside the push block 9. The connecting rod 12 is used to drive the push block 9 to move. The connecting rod 12 is movably connected inside the mounting base 2 3. The mounting base 2 3 plays a limiting role for the connecting rod 12, so that the connecting rod 12 can move smoothly. A limiting block 10 is fixedly connected to the outside of the push block 9. The limiting block 10 is used to limit the push block 9.

[0026] When it is necessary to move the eccentric ring 6, the connecting rod 12 is rotated so that the connecting rod 12 can drive the push block 9 to move upward, thereby driving the eccentric ring 6 to move up and down.

[0027] Example 3: Based on Example 2, in order to improve the effect of the eccentric ring 6 in counteracting high-frequency vibration, an installation groove 8 is provided on the outer side of the inner wall of the slide groove 7. A placement piece 14 is slidably connected inside the installation groove 8. The installation groove 8 limits the placement piece 14, allowing it to slide smoothly. A connecting rod 12 is rotatably connected inside the placement piece 14. A placement block 13 is fixedly connected to the inner side of the placement piece 14. The connecting rod 12 is rotatably connected inside the placement block 13. The placement block 13 and the placement piece 14 limit the connecting rod 12, allowing it to rotate smoothly. The placement block 13 has a limiting groove 11 inside, and the limiting block 10 is slidably connected inside the limiting groove 11. The limiting groove 11 limits the limiting block 10, allowing the limiting block 10 to slide smoothly. The push block 9 is slidably connected inside the limiting groove 11, and the limiting groove 11 limits the push block 9. With the cooperation of the limiting groove 11 and the limiting block 10, the push block 9 can slide smoothly up and down. The connecting rod 12 is fitted with an elastic element 15. One end of the elastic element 15 is fixedly connected to the placement piece 14, and the other end of the elastic element 15 is fixedly connected to the inner wall of the mounting groove 8.

[0028] When vibration occurs, the eccentric ring 6 transmits the vibration force to the placement plate 14 through the connecting rod 12, which in turn causes the placement plate 14 to compress the elastic element 15 and deform, thereby absorbing and canceling the vibration force, and can perform a reset movement, thus waiting for the next vibration force to be buffered.

[0029] The working process of this utility model is as follows:

[0030] When blade 4 is needed, the required number of blades 4 are slid onto the mounting rod 2, ensuring a tight fit between the blades 4 and mounting seat 1. Then, mounting seat 2 3 is slid onto the mounting rod 2, ensuring a tight fit between mounting seat 2 3 and blade 4. Next, by rotating the connecting rod 12, it rotates inside the push block 9. Under the limitation of the limiting block 10 and the limiting groove 11, the push block 9 moves inward, causing the eccentric ring 6 to fit tightly against the outside of the mounting rod 2. This allows the mounting rod 2 to limit the mounting seat 2 3. With the combined limitation of mounting seat 2 3 and mounting seat 1, the blade 4 installation stability is high. When blade 4 vibrates, the eccentric ring... Ring 6 transmits the vibration force to push block 9, which in turn transmits it to connecting rod 12. Connecting rod 12 then transmits the vibration force to placement plate 14 via placement block 13. This causes placement plate 14 to compress elastic element 15, thereby deforming and absorbing the vibration force. It can also perform a reset motion to wait for the next vibration force buffering, resulting in high stability of insert 4 after installation and stacking. Furthermore, eccentric ring 6 can use inertia to cancel high-frequency vibration, and the dynamic balance of the tool can be corrected by moving eccentric ring 6 to adapt to different overhang lengths. This makes the milling cutter highly flexible and stable in use, resulting in high machining accuracy and good economic efficiency.
